Constraints on non-canonical chaotic inflation from ACT DR6 and BICEP/Keck data
Wei Yang, Chen-Hao Wu, Ya-Peng Hu
In this study, we precisely evaluated the feasibility of the chaotic inflation model within a non-canonical kinetic framework. By applying the slow-roll approximation and imposing…
Misner-Sharp Energy and P-V Criticality in Quasi-Topological Cosmology
Yue Chu, Shi-Bei Kong, Yang Liu +2
We presented a sound foundation of thermodynamics for a Friedmann-Robertson-Walker (FRW) universe from the first principle in ground-breaking work [Hu et al., JHEP12 (2022) 168]. B…
Superradiance of rotating black holes surrounded by dark matter
Quan-Xu Liu, Ya-Peng Hu, Tao-Tao Sui +1
In rotating black hole background surrounded by dark matter, we investigated the super-radiant phenomenon of massive scalar field and its associated instability.Using the method of…
Investigating shadow images and rings of the charged Horndeski black hole illuminated by various thin accretions
Xiao-Jun Gao, Tao-Tao Sui, Xiao-Xiong Zeng +2
In this paper, we investigate the shadows and rings of the charged Horndeski black hole illuminated by accretion flow that is both geometrically and optically thin. We consider two…
On the gauge dependence of scalar induced secondary gravitational waves during radiation and matter domination eras
Arshad Ali, Ya-Peng Hu, Mudassar Sabir +1
We revisit the vital issue of gauge dependence in the scalar-induced secondary gravitational waves (SIGWs), focusing on the radiation domination (RD) and matter domination (MD) era…
Gravitational lensing by a charged spherically symmetric black hole immersed in thin dark matter
Xiao-Jun Gao, Xiao-kun Yan, Yihao Yin +1
We investigate the gravitational lensing effect around a spherically symmetric black hole, whose metric is obtained from the Einstein field equation with electric charge and perfec…
Insight into the Microstructure of FRW Universe from a - Phase Transition
Haximjan Abdusattar
The - phase transition of the FRW (Friedmann-Robertson-Walker) universe with a perfect fluid has recently been investigated, revealing that the four critical exponents near t…
Phase Transitions and Critical Phenomena for the FRW Universe in an Effective Scalar-Tensor Theory
Haximjan Abdusattar, Shi-Bei Kong, Hongsheng Zhang +1
We find phase transitions and critical phenomena of the FRW (Friedmann-Robertson-Walker) universe in the framework of an effective scalar-tensor theory that belongs to the Horndesk…
Equation of State and Joule-Thomson Expansion for the FRW Universe in the Brane World Scenario
Shi-Bei Kong, Haximjan Abdusattar, Hongsheng Zhang +1
We study the thermodynamic properties of the Friedmann-Robertson-Walker (FRW) universe in the brane world scenario, concentrating on the Randall-Sundrum II model. From the first la…
The Hawking-Page-like Phase Transition from FRW Spacetime to McVittie Black Hole
Haximjan Abdusattar, Shi-Bei Kong, Yihao Yin +1
In this paper, we investigate the thermodynamics especially the Hawking-Page-like phase transition of the McVittie space-time. We formulate the first law of thermodynamics for the…
Investigating strong gravitational lensing with black hole metrics modified with an additional term
Xiao-Jun Gao, Ji-Ming Chen, Hongsheng Zhang +2
Gravitational lensing is one of the most impressive celestial phenomena, which has interesting behaviors in its strong field limit. Near such limit, Bozza finds that the deflection…
The P-V Phase Transition of the FRW Universe
Shi-Bei Kong, Haximjan Abdusattar, Yihao Yin +2
We define thermodynamic pressure by work density as the conjugate quantity of thermodynamic volume from field equation. We derive the equations of state = f…
First Principle Study of Gravitational Pressure and Thermodynamics of FRW Universe
Haximjan Abdusattar, Shi-Bei Kong, Wen-Long You +2
We make a first principle study of gravitational pressure in cosmic thermodynamics. The pressure is directly derived from the unified first law, in fact the Einstein field equation…
